Publishing packages from CI builds sometimes creates duplication

I want to preface this with the fact that I'm not entirely sure if this is a real issue yet.

Today I was publishing the python package `editables` in a private distribution targeting artifactory from a CI build available here: https://code.launchpad.net/~ubuntu-security/soss/+source/python-editables/+git/python-editables/+build/16087

I published this using the `lpcraft release` command written some time ago by @cjwatson

The package is not currently present in artifactory and it had been around 20-30 minutes, so I wanted to check whether there was something blocking its publication. I created a launchpad client from a python session and checked the private PPA that targets artifactory:

>>> archive = lp.archives.getByReference(reference="ppa:<name of ppa here>")
>>> binaries = [_ for _ in archive.getPublishedBinaries() if _.status in ("Published", "Pending")]
>>> editable_binaries = [_ for _ in binaries if _.binary_package_name == "editables"]

Typically my first check at this point is to make sure there is only one binary (there should only be one version of the package):

>>> len(editable_binaries)
3

So I looked a bit more carefully:

>>> [_.status for _ in editable_binaries]
['Pending', 'Pending', 'Pending']
>>> [_.date_created for _ in editable_binaries]
[datetime.datetime(2022, 12, 8, 18, 53, 29, 267381, tzinfo=TimeZone(0)), datetime.datetime(2022, 12, 8, 18, 53, 29, 267381, tzinfo=TimeZone(0)), datetime.datetime(2022, 12, 8, 18, 53, 29, 267381, tzinfo=TimeZone(0))]
>>> len({url for _ in editable_binaries for url in _.binaryFileUrls()})
1

As you can see they are all 3 'Pending', all published today at the *exact* same timestamp, and share identical URLs.

I gave this a bit more time and the package did ultimately publish, but interestingly there are still 3 packages that turn up, with all 3 indicating they are published now:

>>> binaries = [_ for _ in archive.getPublishedBinaries() if _.status in ("Published", "Pending")]
>>> editable_binaries = [_ for _ in binaries if _.binary_package_name == "editables"]
>>> [_.status for _ in editable_binaries]
['Published', 'Published', 'Published']

Again I have no idea if this is a serious issue but I am not sure if this is intended and wonder if it is a cause of some other issues I've seen with mysterious duplication of released items.
